LOOSE-LEAF BINDER.

Specification of Iiettcrs Patent.

' Application filed February 14, 1920. Serial 110. 358,747.

To all whom it may concern Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Loose-Leaf Binders; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to t e accompanying drawings, forming a part of this specification, and to the merals marked thereon.

My present invention relates to loose leaf or temporary binders for holding separate perforated sheets in book form by the provision of impaling posts upon one book cover cooperating with the-other. and occupying the perforations, and the invention has for its object to provide an improved construction wherebythe capacity of the binder may be readily varied through'the use of inter-- changeable impaling posts ,of differentlengths in conjunction with an adjustable,- .back adapted to be expanded and contracted to suit the length of the posts. To these and other ends the invention resides in certain improvements and combinations of parts all as will be hereinafter-more fully described, the novel features being pointed out in the claims at the end of the specification.

. In the drawings: 4

Figure 1 is a plan view of one'embodiment of my invention, the same being in open position;

Figure 2 is an enlarged sectional view 011 the line 22 of Figure 1;

Figure 3 is an enlarged fragmentary sec-' tional view on the line 33 of Figure 1 with the binder closed, and y t Figure 4: is a view similar to Figure 3 but showing the binder expanded to increase its capacity.

Similar reference numerals throughout the several views indicate the same parts.

Referrin first to Figures 1, 2 and 3, the major parts of the binder consist preferably of a pair of covers A and B connected by an intermediate two-part back C.- The cover members include, in the present instance, connecting members 1- and 2 to which they are hinged at 3 and these cover members are in turn hinged at 4 to the back C. a The hinges referred to may, as usual, consist of the leather or similar flexible covering used to finish the binder .as indicated at 5 in Figure '3. V I

reference nuf a binder con-. structed in accordance with and illustrating One of the connecting members 1 is in the form of a channel and of sheet material forming a guide 6 open at one end to receive a bar 7 that may he slid longitudinally into the same or withdrawn therefrom. The bar carries a pair of impaling posts 8 rigidly fixed thereto as byriveting at 9 and these posts extend through the slot 10 in the top of the channel member., The operative position of the bar and posts is determined by an ear 11 struck up from the floor or the channel at one end, as shown in Figure 2,

and which the end of the bar 7 abutswhen' it is fully inserted. The .bar is then looked in position by a yielding spring latch formed by a tongue 12 also struck from the material of the bottom of the channel member 1 and having a projecting ear 13 engaging the outer end of the bar, as shown in Figure 2.

The other connecting member 2is preferably in the formof. an elongated sheet metal box provided as usual with apertures 14, as shown in Figure 1, to receivethe ends of the impaling posts 8 when the binder is closed, as in Figure 3. The ends. of the posts are notched at 15 forming a shoulder that is engaged automatically, by a sliding bolt 16 within the box-like connecting mem- Patented June 25), 1922.

ber 2 and operated by a spring 17 appearing in Figure 3. The engaging lip of the bolt shows in Figure, 1 and it' may be retracted to release the impaling posts by operating a finger-piece 18 at one end. There is nothing new about this bolt 16 and hence it has not been illustrated in detail. When the two connecting pieces 1 and 2 are locked together in this manner by the impaling posts 8, they havea fixed relationship with each other and with the back C so that they-confine betweenv them the loose leaves on the impaling posts (not shown) and the covers A B open and close on the hinges 3 instead of the hinges 4, the binder being fully extended as in Figure 1, with the covers turning on the-hinges 4 only when it is desired to apply or remove the leaves or pages.

The purpose in. making the impaling posts 8 and their carrying bar 7 removable is to permit them to be interchanged with other posts of greater length than those shown in I Figures 1. 2 and 3 are shown in. place and indicated at 8* in Figure 4. being mounted upon a bar 7. When these larger impaling posts are applied, the back C must also be enlarged or extended for which purpose the two-part construction. mentioned, is used. One part 19 is provided with a plurality of transverse slots 20 in'which are slidable a plurality of bolts 21 secured in the other part 22 and tightened by nuts 23 to hold the two parts of the back in different expanded or contracted positions of relative adjustment. Through the use of this means, the back is shown as of minimum Width in Figure 3 and of maximum width in Figure 4. Preferably the two back pieces are cut away in a complementary manner. as shown. so that their outer faces will be in the same plane and lie flush against the contacting surface.

A binder constructed in accordance with my invention isstrong and convenient to use while possessing sutlicient elasticity in the matter of capacity to properly accom modate widely different quantities of leaves.

I claim as my invention: i

1. In a loose leaf binder. the combination with a pair of covers. of a t\\"o.-part back rigidly connecting them in hinged, relationship. the parts of said back being adjustable one upon the other to change the degree of separation of the two covers. and two detachable interclnlngeable sets of. impaling posts of different length each adapted to be carried by one cover and to cooperate with the other.

2. In a loose leaf hinder. the combination with a pair of covers. of a two-part back rigidly connecting them in hinged relationship. one of said parts being slotted and the other being provided with a fastener cooperating with the slotto maintain the slotted part in different adjusted positions affecting the degree of separation of the covers. and two detachable interchangeable v sets of impaling posts of different lengths each adapted to be carried byone cover and tocooperate with the other.

3. In a loose leaf binder, the combination with a pair of covers, of atwo-part back rigidly connecting them in hinged relation ship. the parts of said back being adjustable one upon the other to change the degree of separation of the covers. and a bar slidaloly' interlocked with one cover and carrying impaling posts cooperating with the other cover.

4. In a loose leaf binder. the combination with a pair of covers. of a two-part back rigidly connecting them in hinged relationship. the parts of said back being adjustable one upon the other to change the degree of separation of the covers. a bar slidably interlocked with one cover and carrying impaling posts cooperating with the other cover. and a latch for releasably looking the bar inposition.

In a loose leaf binder. the combination with a back and a pair of covers hinged thereto. one of said covers embodying a channel member having a guideway paralleling the axis of the hinge. of a bar adapted to be inserted in and removed from the guideway and held thereby interlocked with the channel member. andimpaling posts carried by the bar and cooperating with the other cover member.
